CAUTION: Magnesium-based
flash powders are more sensitive and violent than those made with aluminum.
Individuals inexperienced with flash are encouraged to avoid such compositions.

CAUTION:Calcium metal and calcium
hydride react with water exothermically to evolve hydrogen gas. Compositions
containing calcium metal or calcium hydride should be sealed against moisture
and not be stored.

DANGER: Potassium permanganate mixes
are regarded as sensitive and unstable. They should not be stored under
any circumstances.

DANGER: Chlorate flash mixtures
decompose faster than perchlorate flash mixtures and are more sensitive
to shock, flame, spark and friction.

DANGER: Barium peroxide is unstable
and prone to spontaneous decomposition. Flash mixtures made with barium
peroxide should not be stored under any circumstances, and extreme caution
must be exercised when handling such compositions.

and not be stored.

DANGER: Chlorate and red phosphorus/realgar
mixes are extremely sensitive and highly dangerous, and can explode with
little provocation. Even experienced individuals are encouraged to avoid
such compositions.

DANGER: Chlorate and sulfur/sulfide
mixes are known to be very sensitive to shock, flame, spark and friction.

CAUTION: Magnesium-based
flash powders are more sensitive and violent than those made with aluminum.
Individuals inexperienced with flash are encouraged to avoid such compositions.

CAUTION: Magnesium/teflon
mixtures have been known to ignite spontaneously, however circumstances
surrounding such incidents are not well known. Individuals intending on
making such a composition are urged to exercise extreme caution.

DANGER: Chlorate flash mixtures
decompose faster than perchlorate flash mixtures and are more sensitive
to shock, flame, spark and friction.

DANGER: Barium chlorate is unstable
and prone to spontaneous decomposition. Flash mixtures made with barium
chlorate should not be stored under any circumstances, and extreme caution
must be exercised when handling such compositions.
